Passover marks a time that recounts and celebrates the deliverance of the Children of Israel form slavery as G-d’s Chosen People and when Jesus was crucified for our sins, buried, resurrected, and ascended to Heaven to be with the Father. It is a time when Jew and Gentile can come together to see the blessings that G-d has given us in His Word and means by which we can share the way, the truth and the grace that embodies Jesus.
I pulled together from various sources, including the Messianic Haggadah that we use from the Jewish Voice Ministries which is very detailed in explaining the symbolism of the Passover Seder and its connection to Jesus a document that I use to teach my children. This document (Jesus in Passover) givens an overview of the various aspects of a Seder and their importance and fulfillment in Jesus.
There are many great teachings on the connection of Jesus to the Passover from various Messianic Ministries, including Beth Yeshua International (the one that our family uses), Jewish Voice Ministries, Hebrew4Christians, and many, many more.
I hope that this document is a blessing to your family.
